Protect? Really important? Low level content

I'd say for any dungeon sub-30 it's pretty much optional. Bray, however, is the first dungeon where the difficulty ramps up a bit and the 10% damage reduction isn't something I'd run without if there were new people in the party, especially if either of them was the tank or the healer.

Haukke Manor is actually when the damage becomes real. If you've tanked Haukke you will know how hard groups of these mobs can hit.
